Google could end up paying out 1.35 percent of the money it makes off AdWords in the US after losing a patent suit. On Tuesday, Virginia judge Raymond Jackson set an ongoing royalty rate that Google owes a patent and ringtone company called Vringo in addition to the millions in damages it was ordered to pay last year. The case could theoretically net Vringo hundreds of millions of dollars a year, all because of two patents from the early days of search engines.
